REMOVABLE CAP FOR OIL-CAN S.

Specification of Letters Patent.

Patented Nov. 10, 1914.

App1ioation filed December 1, 1913. Serial N 0. 804,074.

To all whom it may concern Be it known that I, AIBERT E. AINsLIn,citizen of the United States, residing at Brashear, in the county ofAdair and State of Missouri, (whose post-ofi ice address is Brashear,Missouri,-) have invented certain new and useful Improvements inRemovable Caps for Oil- Cans; and I do declare the following to be afull, clear, and exact description of the invention, such as willenableothers skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in removable caps adapted to beapplied to the spouts of oil cans of common construction and its mainobject is to provide a simple, strong and elfective device of thecharacter described which need only be formed in two arts.

With the above and other objects in View, the invention resides in thestructure herein described and claimed and shown in the drawings whereinFigure 1 is a side elevation of an oil can showing my improved capapplied to the spout thereof; Fig. 2 is a similar view, on an enlargedscale, of a portion of the can; and Fig. 3 is a perspective View of theresilient fastening member for the cap.

In the accompanying drawings, I have shown an oil can 1 of ordinaryconstruction being provided with the usual spout 2.v Although forming nopart of the present invention, these parts closely coact therewith.

Coming now more particularly to details, the numeral 3 designatesbroadly a coil spring which as shown, has its lower end reduced as at 4:for a purpose to appear.

The free upper end of the wire forming the spring 3 is bent upwardly asat 5, formed with a hook 6, then extends downwardly and to the oppositeside of the spring where it isgiven a plurality of coils 7 around theyupper convolution of the spring 3. This end then extends upwardly fromthe coil 7, is formed into a hook 8 and then projects downwardly and issecured at 9 at a point above the spring 3.

A cap 10 having a depending flange 11 and being provided'with a packing12 on its inner side is adapted ,to seat over the open end of the spout2. Said depending flange is provided with oppositely disposed openings13 through which pass the hooks 6 and 8 carried by the spring 3.

In practice, the reduced end A of the spring 3, is made of slightly lessdiameter than the diameter of the spout to which it is to be applied,while the upper portion of the spring 3 is of considerably greaterdiameter than the spout 2. Thus it will be seen that by unwinding thecoils of the spring 4 to a proper extent, said spring may be slippedover the spout 2 and on account of its size, it will securely hold thedevice upon said spout 2. It will then be obvious that the upper portionof the spring 3 is free to expand when it is desired to remove the cap10.

Although I have shown the retaining and expansion springs and thevertical arms of my device as formed of one piece of wire, it will beobvious that I need not be limited to this construction.

The caps and retaining springs may be formed in any number of sizes forapplication to different sized can spouts but, I find that bymanufacturing them in three sizes, they will accommodate most cans .onthe market.

What I claim is: v

A removable closure for can spouts comprising a cap having oppositelydisposed apertures in the sidewalls thereof, a coiled spout-encirclingspring composed of a single strand of wire coiled to form a larger and asmaller end, the small portion being of uniform diameter throughout,said wire being extended longitudinally at opposite sides of the outerconvolution of the larger portion and bent to form loops provided attheir outerends with hooks, the outer terminal of said wire being coiledaround the v outer convolution of the larger portion of the coil andthen around the portion connecting the hook-carrying loops, said hooksbeing adapted to detachably engage the ap- ALBERT EDWARD AINSLIE.
